A pumping station powered by Delta CP2000 frequency drives is delivering environment friendly irrigation to a dairy farm in South Africa in an area experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make certain that the water dropped at the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a reliable and cost-effective water provide. The farm’s owner commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session course of, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be filled with water by a total of six underground well pumps overnight, when the vitality costs have been low. A transport pump is used to transfer water from the decrease reservoir to the upper one. The peak difference allows the sprinkler system to be operated utilizing gravity alone during the day, making it significantly efficient. The farm animals and the dairy can even take their water supply from this irrigation system. The key necessities of the venture had been cost effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water delivered to the surface is transferred on to the higher tank. The CP fashions characteristic a PID controller with suggestions that permits the water degree in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and continually monitoring the circulate. If the borehole stage falls under a minimal predetermined by the consumer, the PLC control switches to the following the borehole and prevents the pumps from being broken.
The system has various Delta DVP collection programmable logic controllers (PLCs). เพรสเชอร์เกจ in boreholes and hold the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level in the high reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all of the processes in the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software additionally permits the time configuration and vitality costs to be monitored remotely. Users can even monitor the whole course of by way of the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with enough water, even in periods of low rainfall.
